A dungeon crawl is a type of scenario in fantasyrole-playing games in which heroes navigate a labyrinthine environment (a "dungeon"), battling various monsters, and looting any treasure they may find. Because of its simplicity, a dungeon crawl can be easier for a gamemaster to run than more complex adventures, and the "hack and slash" style of play is appreciated by players who focus on action and combat. The term can be used in a pejorative sense, since dungeon crawls often lack meaningful plot or logical consistency. For example, the parody game Munchkin is about "the essence of the dungeon experience… Kill the monsters, steal the treasure, stab your buddy."[1]

The first computer-based dungeon crawl was pedit5, developed in 1975 by Rusty Rutherford on the PLATO interactive education system based in Urbana, Illinois. Although this game was quickly deleted from the system, several more like it appeared, including dnd and Moria.

Some distinguish "dungeon crawlers" from rogue-likes and RPGs with stories and character-interaction, while others use the term to describe any game which features ample amounts of dungeon exploration (including Zork, Zelda and tabletop RPGs). More recently the term has come to mean 1st person RPGs, particularly ones which are aligned to a grid system and can be mapped on graph paper.

According to Gary Gygax (in an interview with Dungeon #112), the first dungeon crawl was part of a wargame in which the invading force entered the enemy's castle through a former escape tunnel dug from the fortress's dungeon. The group had so much fun with this scenario that it was repeated over and over with increasingly complex dungeons until the wargame aspect of the game was dropped in favor of exploring the dungeon.

Due to their potential for simplicity and the limited expectations most players have for plot and logical consistency in dungeon crawls, they are fairly popular in role-playing video games.[citation needed] The roguelike genre is a common and typical example, with endless procedurally generated dungeon terrain and randomly placed monsters and treasures scattered throughout.

^Edge Staff (2012-04-12). "Legend Of Grimrock review". Edge. Retrieved 2012-05-09. Legend Of Grimrock isn't a love letter to Dungeon Master, the 1987 blend of subterranean exploration, survival, switches and traps. It's a near-facsimile. But that's not a fact Almost Human is trying to hide; it's the selling point. Legend Of Grimrock replicates a classic faithfully enough to massage the nostalgia glands of anyone who played the original, and it's a test of the timelessness of an almost universally loved game.
